What is the principle of credit card skimming?

The principle of credit card skimming is that someone else steals your credit card or your credit card information, and then conducts transactions through your credit card. Or obtain your credit card's magnetic stripe information, create a new credit card, and then use the card swiping device to make purchases. There are many ways to obtain credit card magnetic stripe information. For example, when you make a purchase, someone uses a card reader to read the information, or when you pay online, the information is stolen. Today's magnetic cards are easy to read and write if stolen.

The reasons for credit card swiping may be that the credit card is lost and swiped, or it may be caused by the leakage of credit card information, or someone may have stolen your credit card. The cardholder does not need to repay the debt due to credit card fraud. Under normal circumstances, the debt owed by credit card fraud is borne by the perpetrator, and the public security organs will recover the stolen money. Therefore, when encountering credit card fraud, cardholders must report the case in time to avoid greater losses.

How credit cards are stolen.

1. The card is swiped

When swiping a credit card, the payee needs to perform a "swipe" action on the card swiping machine. And some people may take advantage of this time to use a machine similar to a credit card machine to steal your card. When you enter your password, it may have been monitored. In this way, after the other party issues a new card and knows your password, they can steal your credit card.

2. The number on the back of the card is leaked

There are 7 digits on the back of the credit card, which are the 7 digits on the magnetic strip. The last three digits of this 7-digit number are also called CVV2. Some online payments only require these 7 digits or CVV2, plus the validity period of the card to make the payment. Therefore, if the number on the back of the card is leaked or peeked by someone when using the card, they will use this method to steal your credit card.

3. Enable password-free payment

If you are a person who often uses credit cards, you like to pay with credit cards no matter how large or small. For example, when you go to the supermarket to buy hundreds of items quickly and use a credit card, for convenience, you may enable PIN-free payment for small or large amounts. We know that in addition to magnetic stripe cards, credit cards also have chip cards. Chip cards do not need to be swiped in the card slot of the card swipe machine like magnetic stripe cards. Instead, they can be placed directly on the card swipe machine and the payment will be made, just like usual. Just like a subway card, you can pay with just one tap without entering a password. And some people will take advantage of this convenience and bring some kind of machine to rub against you in a crowd, or when you are crowded in the subway or bus, so that you can steal your credit card.

4. Bind with WeChat or Alipay

As popular as credit cards, there are WeChat payment and Alipay payment. For convenience, most people bind their credit cards to Alipay or WeChat. We also know that surveillance is installed in many places. If someone accidentally peeks into your WeChat or Alipay password when paying, they can log in to your WeChat or Alipay and steal your credit card.

5. Clicked on the link with the virus

Everyone knows that Internet red envelopes are red envelopes sent through the Internet. After you click on them, you can receive the payment from the other party. In addition to sending red envelopes to friends, you can also send red envelopes to strangers in QQ groups and WeChat groups. Of course, strangers can also send red envelopes to you. And some people will take advantage of the pie-in-the-sky thing to send you red envelopes or links to get money. After you click on these links, the other party may install viruses on your phone or computer and steal your passwords. Wait, so that your credit card can be stolen.

6. The verification code was leaked

When we consume online, there is a consumption method called quick payment. You do not need to log in to WeChat or Alipay. Enter the last 6 digits, and then Enter the password verification code and you can pay immediately. Because the password of a credit card is 6 digits, some people may set the password to birthday, mobile phone number, etc. for convenience. These passwords can be easily deciphered. Once the password is cracked, only the verification code is left. If you inform someone of the verification code online or over the phone, the other party can steal your credit card.

7. The mobile phone has been used by others

Sometimes, we will meet friends or strangers who say to you: The phone is out of battery, the phone is missing, I can borrow your phone to make a call. one time. After you lent your phone, you didn't stare at the other person all the time. This kind of embarrassment may be taken advantage of by some people. He can get your verification code through the mobile phone, or use your Alipay or WeChat to pay directly. After using it, delete the payment records and text messages. Just like that, your credit card was stolen without you being prepared.

8. Mobile phone or mobile phone number is stolen

Nowadays, mobile phone number is like people’s ID card, which is becoming more and more important. This is because a mobile phone number is not only a tool for people to communicate with each other, but more often than not, it is because the mobile phone number is bound to a bank card. Through the mobile phone number, you can modify the password of the bound bank card, and you can also make various modifications to the bound login account.
